2.6. Brake Power Supply (TB103)
TB103 is the power supply connection to the onboard solid state brake control relay.
The relay can be used to automatically control a fail-safe brake on a vertical axis. It can also be used as a
general purpose output.
The brake is typically wired directly to the Motor Feedback connector and the brake power supply is
connected to TB103 (shown in
Figure 2-43
. The brake may also be connected in series with the Brake Power
Supply and interlocked using Motor Feedback brake pins (
Table 2-43
and
Figure 2-44
).
A varistor must be connected across the brake to minimize high voltage transients.
The brake output can be software configured; refer to the Ensemble Help file for more information (see topics
for the EnableBrakeControl parameter and the BRAKE command).
When TB103 is used to power the solid state brake control relay, the mechanical brake control relay present
on the I/O board should not be used.
N O T E :
The brake power supply must be externally fused.
